I had a tulip "deliter" that needed replacement the other day with a broken bell. they had a ton of these, and although I am not a fan of the bayonet base, and I think the spread could be better on these with a better curve of the stem, I went ahead and just ordered one for a replacement. Folks that read my posts know I am not a Nightscaping fan, but If they are in good shape and look like they have life left in them, I do try to keep them, and re-use them in designs if possible. I have not gotten any new fixtures from them in a few of years however, and when I opened the box, I was surprised to find those yellow wire nuts. my guess is in NS workshops they train folks to seal those with something, but still, why do they still use these? In this particular add on/install, she probably had over 50 NS fixtures, and upon inspecting the connections made 2years ago, all of them used this wire nut, with no sealer, and corrosion had already begun, that wonderful, all too familiar blackish greenish color, even though they did the "tuck them in the stem/stake/pipe" thing. can someone tell me why they don't at least provide a grease wire nut? grease wire nuts have been around for over 20 years! I will stand up and give a shout out to NS for one thing. These are the first NS trans I have found that still had loaded voltage ( one had 320 watts and the other 360 ) to spec in the last 5 NS powercenter installs I have found. one was a multi tap and the other a straight, both 500 watters. only 2 years old. With her add on, I upgraded her to 2, 900 watt true multi tap to get her older fixtures to 10.9 to 11.7 or so. If anyone wants these used NS units, pm me.
